Unit Three Study Guide

Chapter 10

  • Know the basic structure of a plant's leaf (mesophyll cells, stomata)
  • Know the basic chemical equation of photosynthesis
  • Know that water is split to provide electrons, and later reformed
  • Know that photosyntheis is the reduction of Carbon Dioxide to form Glucose
    • (know what reduction/oxidation means) OIL RIG
  • Know the reactants and products of the light reactions
  • Know what a photosystem is and how energy is passed to the reaction center
  • Know the basics of non-cyclic and cyclic electron flow
    • What does each synthesize? 
    • Be able to trace the path of electrons from water to NADPH
    • Know why cyclic electron flow is necessary
  • Know the basics of chemiosmosis and how ATP is produced
  • Know the reactants and products of the Calvin cycle, as well as where it takes place
  • Know what organic molecule is actually created by the Calvin cycle
  • Know the 3 basic steps of the Calvin cycle (Carbon fixation, reduction, regeneration of RuBP)
  • Know the basics of C4 plants and CAM plants, and why these mechanisms have evolved

Chapter 9

  • Know the basic equation for Cellular Respiration
  • Know the structure of ATP, and why it is used as our energy carrier
  • Know that ATP is recycled from ADP and Pi, not made from scratch every time
  • Know OIL RIG (what oxidation/reduction mean)
  • Know that glucose is oxidized to Carbon Dioxide in cellular respiration
  • Know that each step of this process is catalyzed by enzymes
    • We have to control the reaction so that we can harness the energy
  • Know the role of NADH and FADH2
  • Know the role of oxygen in cellular respiration and what molecule the O2 ends up in
  • Know the basics of glycolysis - the products and reactants
  • Know how the product of glycolysis is altered before entering the Krebs cycle
  • Know the products and reactants of the Krebs cycle
  • Know how electrons get from Glycolysis and the Krebs cycle to the Electron Transport Chain
  • Know the location of the ETC, and how electrons falling down the chain produce energy (chemiosmosis/oxidative phosphorylation)
  • Know the difference between Aerobic and Anaerobic respiration
  • Know the 2 types of fermentation and what they produce
  • Know that other types of macromolecules can be used in cellular respiration
  • Know that respiration is controlled by feedback inhibition
